Solution - Linear equations with one unknown

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                     10^7*x-(75)=0 

Step by step solution :

Step  1  :

 1.1     10 = 2•5

(10)⁷ = (2•5)⁷ = 2⁷ • 5⁷

Equation at the end of step  1  :

  ((27•57) • x) -  75  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   2⁷ • 5⁷x - 75  =   5 • (2x - 15) 

Equation at the end of step  3  :

  5 • (2x - 15)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    5   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 4.2      Solve  :    2x-15 = 0 

 Add  15  to both sides of the equation : 
                      2x = 15
Divide both sides of the equation by 2:
                     x = 15/2 = 7.500
